Answer:

PLS MARK ME AS THE BRAINLIEST

\frac{49}{2}

Step-by-step explanation:

Length of the diagonal = 7cm

Let the side length be x

According to pythagorean theorem x²+x² = 7²

2x² = 49

x² = \frac{\sqrt{49} }{\sqrt{2} }

= \frac{7}{\sqrt{2} }

Area of the square = \frac{7}{\sqrt{2} }×\frac{7}{\sqrt{2} } = \frac{49}{2}
